Finnish quantum hardware developer SemiQon has secured a strategic equity investment from PostScriptum, the specialized founder’s office directed by technologist Peter Sarlin (Co-Founder of Silo AI). The financial injection directly supports the commercial scale-up and volume manufacturing of SemiQon’s proprietary silicon-based Cryo-CMOS control and readout microchips. Coinciding with the transaction, PostScriptum announced a comprehensive €30 million ($34.35 million USD) capital commitment dedicated explicitly to financing foundational hardware layer technologies—such as cryo-electronics, advanced sub-kelvin attenuation, and cooling modules—required to transition quantum computers into the million-qubit execution era.
[ SemiQon Operational Infrastructure ]
Spin-Out Origin ──► VTT Technical Research Centre of Finland Ltd (Transitioned to market in 2025).
Manufacturing Base ──► Micronova Center for Applied Micro and Nanotechnology (Espoo, Finland).
Platform Topology ──► Cryo-CMOS chips removing bulky wiring lines inside localized cryostats.
SemiQon’s hardware platform addresses one of the primary scaling bottlenecks hindering deep-tech computing: the complex, heavy coaxial wiring assemblies traditionally required to route signals between sub-millikelvin quantum processors and room-temperature control racks. Spun out from the VTT Technical Research Centre of Finland Ltd and manufactured on-shore at the Micronova fabrication facility in Espoo, the company’s cryo-optimized silicon integrated circuits operate directly inside the ultra-cold environment of the cryostat. By positioning the primary readout and control electronics directly adjacent to the qubits without introducing thermal or magnetic interference, the chip architecture shrinks the physical physical footprint of the interconnect layer, facilitating a modular scaling path from hundreds of qubits to millions.
A major commercial advantage of SemiQon’s technology lies in its native structural compatibility with standard, high-volume complementary metal-oxide-semiconductor (CMOS) manufacturing lines. Rather than relying on custom, boutique fabrication facilities, the chips are designed to be mass-produced using the exact lithography equipment, silicon wafers, and testing parameters utilized by traditional global microchip foundries. This manufacturing framework allows SemiQon—led by Co-Founder and CEO Himadri Majumdar—to deliver multi-modality hardware subsystems to third-party quantum computer OEMs and system integrators globally, while serving cross-industry demand across autonomous space tech and high-performance computing (HPC) fields.
[ PostScriptum Corporate Matrix ]
Venture Sponsor ──► Peter Sarlin (Silo AI Co-Founder; Professor of Practice at Aalto University).
Executive Lead ──► Antti Vasara appointed as VP of Quantum (Former President and CEO of VTT).
Strategic Focus ──► Building sovereign European control electronics and sub-kelvin hardware layers.
To drive its broader quantum portfolio, PostScriptum has appointed Antti Vasara as Vice President of Quantum to oversee its deployment pipelines. Vasara, who also serves as Chair of the Board at SemiQon and is the former President and CEO of VTT, brings deep microelectronics commercialization experience to the investment firm. His addition reinforces PostScriptum’s positioning alongside its existing deep-tech incubations—including the newly launched quantum-AI lab Qutwo—establishing a vertically integrated European technology hub capable of manufacturing sovereign control electronics and solidifying Finland’s positioning within global supply chains.
